  • Great upgrade for a sleeper sofa.
Size: (58.5”x76” Full Covered Queen Size)
We eliminated our guest room and got a sleeper sofa as an optional spare bed for visitors. While looking around on Amazon for ways to improve our sofa bed, this item was suggested to me. I never knew something like this existed but I bought it on whim to try it out. It’s easy to use but a little bulky to move around by yourself so you may want to have someone else present to help you. It’s sturdy, prevents the springs and various support bars in a foldout couch from digging into your back. Our guests stated they slept well. Our sleeper sofa is a queen size. I didn’t measure anything and thankfully this fit perfectly. It was the exact size needed. It was actually a little longer than the mattress but he added height prevents the foam mattress from folding over the edges. When you’re done it folds up and stores easily in a closet or behind the couch. (You can’t fold it in with the mattress, unfortunately.) We kept the original box because we move a lot and I’d be concerned how it would hold up in an move without the outer box protecting it. Overall, I would recommend this product. Especially if you plan on sleeping on your sofa bed regularly. ... show more

  • Good board
Size: (46”x76” Full Covered Full Size)
Worked good for my guest room platform full size bed. Width a little shorter that entire bed frame, but supports good.

  • Meh — Slightly Better Than Nothing, But Not by Much
Size: (58.5”x76” Full Covered Queen Size)
The NobleRealm® Better Size Sleeper Sofa Board is... fine. It does make the pull-out couch a bit more comfortable, but don't expect a miracle. You can't feel the bars underneath, but it's still not terribly comfortable. Probably more of a mattress thing.... What really threw me off was the chemical smell straight out of the box—strong and unpleasant. In short: it’s marginally helpful. ... show more

  • MEASURE BEFORE ORDERING BUNKIE BOARD
Size: (33”x58.5” Twin Size)
Better yet.. Just skip this product. I ordered this for a twin size loft bed. I’ve never really had to measure stuff for a bed. These are pretty basic measurements, so I ignored the reviews and took a chance. It was obvious out the box that this bunkie board was too small. Just quickly measuring for reference, but close enough. The board measures about 33”W x 58”L .. the bed measures about 40”W x 77”L .. It’s not even close. This would probably fit my toddler’s bed. Their full size would almost fit a twin except it’s 48”W.. Close, but nope. The fabric that covers the board seems decent quality and definitely stays in place, but it’s baggy, so once the mattress was placed on it, the fabric kind of sags through the bars. We needed the board asap, so I could try and see if it will work, but I’m returning it because since it only sits in the middle of the frame, it made it sag even more. For the seller: A bunkie board should fit the entire frame for extra mattress support. It’s wrong to advertise and sell a product that you know isn’t going to fit. The picture shows how much smaller it is than the bed itself. ... show more

  • Wrong size
Size: (58.5”x64” Queen Size)
Only returned it because I ended up not using it, but I’ve heard it was awesome from other reviews

  • Not as advertised
Size: (58.5”x80” Full Covered Queen Size)
Board thickness is less than advertised. While claiming 8mm (thicker than the 6mm “competition”) the actual thickness of the compressed wood is less than ¼” (closer to the competition) and seems flimsy. Further it is not as large as advertised, falling several inches short of the 80” claimed even stretching the fabric cover to the max. Quality control is poor, with stitching unraveling. Hopefully it will do the job and not break with the flexing of the bed slats. ... show more

  • Not true to size description.
Size: (46”x76” Full Covered Full Size)
The description states that it will fit a full/double bed and it did fit length wise, but the width was short about 3 to 4 inches on each side (would be good for a twin size bed). It is extremely thin, so it will not replace a true Bunky board for a platform bed but I could see how it would be helpful for a pull out couch. ... show more

  • Functional

Worked great for my makeshift pallet bed. No complaints on durability, function or sturdiness. Supports the mattress great and arrived on time!
